The more teens—especially girls—weigh themselves, the more likely they’ll have a negative perception of their bodies, according to a new study published in the Journal of Nutrition Education and Behavior.

Researchers talked with approximately 2,000 adolescents about their bodies and asked whether they had any particular concerns regarding their physical appearance. They also asked them how often they weighed themselves. They discovered—perhaps not-so-surprisingly—that the more teen girls tended to measure their weight, the more concerned they were about their weight.

“Adolescent obesity is a great public health concern,” dietician and lead researcher Carly Pacanowski said, “but at the same time, body dissatisfaction and self-esteem can be predictors of eating disorders. By investigating this connection, we hope there will be better-designed studies to further identify people for whom weighing is not a great strategy and for whom other prevention methods may be more helpful.” (Time)
